How do you pass a parameter to a method from nant? The nant method can take a project as parameter why not take any other type parameter?
http://nant.sourceforge.net/release/0.85/help/tasks/script.html
The example give in the question takes zero arguments.
Month name in NAnt
<property name="build.date" value="${datetime::parse('2014-07-29 10:21:02')}" />
<property name="build.month" value="${utils::GetMonth(${build.date})}}" />
[Function("GetMonth")]
public static string GetMonth(DateTime date)
{
return date.ToLongDateString().Split(new Char[]{' '})[1];
}
You should avoid the second pair of curly braces, like this:
<property name="build.month" value="${utils::GetMonth(build.date)}" />
In case there's a problem passing DateTime, you can try switching to string parameter instead and parse it the proper way in the C# code.

By default Spring MVC assumes #RequestParam to be required. Consider this method (in Kotlin):
fun myMethod(#RequestParam list: List<String>) { ... }
When passing empty list from javaScript, we would call something like:
$.post("myMethod", {list: []}, ...)
In this case however, as the list is empty, there is no way to serialize empty list, so the parameter essentially disappears and so the condition on required parameter is not satisfied. One is forced to use the required: false on the #RequestParam annotation. That is not nice, because we will never receive the empty list, but null.
Is there a way to force Spring MVC always assume empty lists in such case instead of being null?
To get Spring to give you an empty list instead of null, you set the default value to be an empty string:
#RequestParam(required = false, defaultValue = "")
This can be managed in the serialization with ObjectMapper. If you are using jackson in your spring MVC, you can do either the following.
1) Configure your object mapper:
objectMapper.configure(SerializationConfig.Feature.WRITE_EMPTY_JSON_ARRAYS, false);
2) Or if you are using beans via xml config:
<bean name="objectMapper" class="org.springframework.http.converter.json.JacksonObjectMapperFactoryBean" autowire="no">
<property name="featuresToDisable">
<list>
<value type="org.codehaus.jackson.map.SerializationConfig.Feature">WRITE_EMPTY_JSON_ARRAYS</value>
</list>
</property>
</bean>
You can try a WebDataBinder in your controller.
#InitBinder
public void initBinder(WebDataBinder binder) {
binder.registerCustomEditor(List.class, "list", new CustomCollectionEditor( List.class, true));
}
Tried this?
fun myMethod(#RequestParam list: List<String> = listOf()) { ... }
I have one document template as like attached screen shot. now my requirement is i want to dynamically update some values of that document when i will upload it in alfresco site. i will either create that Document through node template or upload. I want to provide those values from document property page.
can anyone help me how can i achieve this.
I tried it using java script, but i am getting some problem. so i am thinking for using Alfresco CMIS API. But i am quite new in alfresco cmis. so can any one tell the better way which i can use for this task.
Thanks in advance.
I think you should trigger an custom action by a Rule
When someone update a node (for example by editing properties), your action will be triggered and you will be able to :
get the content of your node
get the properties of your node
use the apache poi library provided by alfresco (my guess is that you use word documents) to find your parameters, and the replace them by the value you find in the property nodes.
Here is an excellent tutorial to learn how to create a custom action.
Note : You may have to keep the original templated document if you want to change a second time your properties (by using versionning for example).
Edit (see discussion below) :
I assume you know how to use rules in alfresco : http://docs.alfresco.com/5.0/tasks/library-folder-rules-define.html
Declare a new action to assign to a rule. This action must be triggered when the excel is dropped or updated
Create an action implementing your need :
public class MyAction extends ActionExecuterAbstractBase {
...
#Override
protected void executeImpl(final Action arg0, final NodeRef arg1) {
// your code here
}
....
}
This action will :
Take the nodeRef parameter (which is the excel file) and load the file
...
Inputstream inputstream = getFileFolderService().getReader(arg1).getContentInputStream();
...
NPOIFSFileSystem fs = null;
HSSFWorkbook workbook = null;
try {
fs = new NPOIFSFileSystem(inputstream);
workbook = new HSSFWorkbook(fs.getRoot(), true);
//get your data with POI
For each row of your excel :
Make a copy of your template :
find it :
getSearchService().query(searchParameters)
copy it :
getFileFolderService().copy(sourceNodeRef, targetParentRef, newName)
Do transformations of your new word content (Find occurrences and replace with poi library).
Update the content of your new file :
ContentWriter writerDoc = getContentService().getWriter(document.getNodeRef(), ContentModel.PROP_CONTENT,
true);
writerDoc.putContent(file/inputStream);
In your context file, declare you action :
<bean id="my-action" class="x.y.z.MyAction" parent="action-executer">
<property name="searchService">
<ref bean="searchService" />
</property>
<property name="nodeService">
<ref bean="nodeService" />
</property>
<property name="contentService">
<ref bean="contentService" />
</property>
<property name="fileFolderService">
<ref bean="FileFolderService" />
</property>
....
</bean>
In Share, assign to a folder a rule with the action you have created.
I am using Hibernate Validator as a JSR-303 validation provider and its xml style constraints descriptions.
So, I have a
<bean class="com.my.User" ignore-annotations="true">
<field name="email">
<constraint annotation="javax.validation.constraints.Pattern">
<element name="regexp"><![CDATA[[A-Za-z0-9\._%+-]{1,64}#[A-Za-z0-9.-]+\.[A-Za-
z]{2,4}]]></element>
</constraint>
</field>
.....
</bean>
I also have a separate class, which contains all my patterns
public final class Regexps {
public static final String EMAIL_REGEXP = "A-Za-z0-9\._%+-]{1,64}#[A-Za-z0-9.-]+\.[A-
Za-z]{2,4}";
....
}
So, as you can see, I have two places, where email regexp is present, and I want only one place.
My question:
Is it possible to use the
public static final String EMAIL_REGEXP = "A-Za-z0-9\._%+-]{1,64}#[A-Za-z0-9.-]+\.[A-
Za-z]{2,4}";
field inside the xml, so that
I could just refer to the contant string field.
So I would Like to have something like:
<bean class="com.my.User" ignore-annotations="true">
<field name="email">
<constraint annotation="javax.validation.constraints.Pattern">
<element name="regexp">Regexps.EMAIL_REGEXP</element>
</constraint>
</field>
.....
</bean>
By the way, it is possible via annotations
public class User {
#Pattern(regexp = Regexps.EMAIL_REGEXP)
private String email;
}
But I cannot use annotations, because I use the legacy POJOs which I use for data transfering and cannot change the source code.
Currently it's not possible to reference constraints from within XML constrained mappings. I think it's a good idea, though. Could you open a feature request in our issue tracker so we can discuss the feature there?
If you can't use annotations, you might give Hibernate Validator's API for programmatic constraint declaration a try, you could then work with a shared constant for the pattern.
I am going to escape HTML in Spring MVC with Jackson Mapper to avoid XSS attack. I search for escaping with Jackson alone and how to config Jackson in Spring. I tried to export json with text like "<" ">", I expected it to escape them to < and >. For example, I added some text enclosed with "bold tag" <b>, I expected to see plain bold tag text in the front end html but it ended up so that the text is shown in bold style in the front end html page.
Below is my approach. I don't know why it didn't work out.
public class CustomObjectMapper extends ObjectMapper {
public CustomObjectMapper() {
this.getJsonFactory().setCharacterEscapes(new CustomCharacterEscapes());
}
}
public class CustomCharacterEscapes extends CharacterEscapes {
private final int[] asciiEscapes;
public CustomCharacterEscapes() {
int[] esc = CharacterEscapes.standardAsciiEscapesForJSON();
esc['<'] = CharacterEscapes.ESCAPE_STANDARD;
esc['>'] = CharacterEscapes.ESCAPE_STANDARD;
esc['&'] = CharacterEscapes.ESCAPE_STANDARD;
esc['\''] = CharacterEscapes.ESCAPE_STANDARD;
asciiEscapes = esc;
}
#Override
public int[] getEscapeCodesForAscii() {
return asciiEscapes;
}
#Override
public SerializableString getEscapeSequence(int ch) {
return null;
}
}
Here is the Spring Bean configuration:
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<array>
<bean id="jsonConverter"
class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
<property name="objectMapper">
<bean class="x.y.z.CustomObjectMapper" />
</property>
</bean>
</array>
</property>
</bean>
I have never tried to write my own HttpMessageConverter, but I did find this posting that seems pretty relevant to what you want to do. In looking at their solution vs. what you posted here, I can say the biggest differences I noticed was that you did not seem to implement/override the following:
protected boolean supports(Class<?> clazz), which indicates which class type you are supporting (I would recon in your case this would be Object or Serializable if you want it to be generic enough to handle every possibility, or some class specific to your domain objects)
protected Object readInternal(Class<? extends Object> clazz, HttpInputMessage inputMessage), looks like it's used for the request-side
protected void writeInternal(Object t, HttpOutputMessage outputMessage), which looks like it's used for the response-side
Another approach might be to simple create a custom Jackson serializer in conjunction with #ResponseBody. Or, better yet, if you have a value that is user-driven, and your storing it in a database, escape the values prior to insertion. That way you don't need to do anything at all, and the value(s) in question would be "safe" from end-to-end. If you wanted to get crazy-fancy, you could write a custom java.beans.PropertyEditor that escapes Strings for HTML and plug that into the mix using the InitBinder.
Finally, I would like to recommend that, instead of trying to replace the characters on your own, you use something like Apache Commons-Lang's StringEscapeUtils to escape the values.

ASP.NET - Storing SQL Queries in Global Resource File?
I want to do something like the above link...but it is not working for me..
I have dynamic sql in my project which i want to move to xml. Can some one please help?
I really hope that you saying you want to store "SELECT BookingID from BOOKING WHERE BOOKINGDATE >= {0}" doesn't mean you are planning on writing:
String.Format(query, parameter)
That's a huge security vulnerability.
Edit:
If you really want to go down this route I would suggest Xml like:
<queries>
<query id="getBookingId">
<parameters>
<parameter name="bookingDate" />
</parameters>
<statement>
<!--
SELECT BookingID from BOOKING WHERE BOOKINGDATE >= #bookingDate
-->
</statement>
</query>
</queries>
Then you can have a class:
[XmlElement("query")]
public sealed class Query
{
[XmlAttribute("id")]
public string Id { get; set; }
// other elements/collections
}
You can then deserialize your Xml into a collection of these Query objects. I would recommend doing this once and storing it in an IDictionary somewhere to avoid repeatedly processing an Xml file.
You then have everything you need in each Query object. A collection of parameters and the sql statement - note that you'll have to manually strip the comment characters () out of the statement before using. Again, probably best to do this once at the beginning.
